Fan-Gate，Like-Gate，show-to-connections，javascript和like box？ [英] Fan-Gate, Like-Gate, show-to-connections, with javascript and like box?

问题描述

我的网站上有一个facebook likebox（不是iframe应用），我需要创建封闭内容。我理解FB.Event.subscribe使用edge.create和edge.remove但我真正需要的是知道用户是否已经喜欢该页面，而不仅仅是他们成为粉丝或不再是粉丝。有没有什么我可以看到作为回调可能来自xfbml.render？

I have a facebook likebox on my site (not an iframe app) where I need to create gated content. I understand the FB.Event.subscribe using edge.create and edge.remove but what I really need is to know if a user already likes the page not simply if they became a fan or stopped being a fan. Is there anything I can see as a callback maybe from the xfbml.render?

我受限于（由我的公司）使用前端语言，这意味着javascript真的是我的此时只有选项。我很乐意使用signed_request选项，但最好的我可以说它似乎只能通过服务器端语言访问。

I am limited (by my company) to using front end languages, meaning javascript is really my only option at this point. I would gladly use the "signed_request" option but best I can tell that seems to be only accessible via server side languages.

有没有办法让我确定是否有人已经只使用javascript喜欢一个页面？

Is there any way for me to determine whether someone already "Likes" a page using only javascript?

推荐答案

是的，您可以使用FB Javascript sdk在javascript中完成此操作。

Yes, you can do this completely in javascript using the FB Javascript sdk.

function RunLikeCheck() {
var likeId = 'yourLikeIdHere';
    FB.api({
        method: 'fql.query',
        query: 'SELECT uid FROM page_fan WHERE page_id = ' + likeId + ' AND uid = me()'
    },
                function (response) {

                    if (response.length == 1) {
                        $("#HasLiked").val('true');
                        $('#frmAllow').submit();
                    }
                    else {
                        $("#HasLiked").val('false');
                        $('#frmAllow').submit();
                    }
                }
            );
}

现在假设您已经让用户登录并拥有正确的权限。

Now this is assuming that you already have the user logged in and have the correct permissions.
